MEDICATED PLASTER.

EPECIFICATION formingpart of Letters Patent No. 733,504, dated July 14, 1903.

Application filed September l5, 1902.

To @ZZ 'Lohan/z, it may concern:

Be it known that'I, FREDERIC J. NASH, a citizen of the United States, residing in the borough of Brooklyn, city and State of New York, have invented certain new and useful Improvements in Medicated Plasters, of which the following is a specication accompanied by drawings.

My invention relates to medicated plasters; and its objects are to improve upon such plasters heretofore in use.

Having found that no plaster has ever had the action of the cup, the object of my invention is to secure the benefit of the cup with none ofits objections, and this is accomplished with myimproved medicated plaster.

My improved plaster has every benet that the cup would ever give to the patient, and having now briefly set forth the objects of my invention, while further objects will hereinafter appear, my invention consists in a plaster for carrying out the above objects constructed and having the general mode of operation substantially as hereinafter fully described in this specification and shown in the accompanying drawings, in which- Figure l is a perspective View ofv a portion of a plaster embodying my invention, shown partly in section. Fig. 2 is a top plan view of a modification of my plaster Without the perforated edges. Fig. 3 is a perspective view of another modification provided with a cap. Fig. 4 is a transverse sectional view of Fig. 3, and Fig. 5 is a sectional view of a modification.

Referring to the drawings, a piece of cloth A, faced with rubber B or any other suitable material, is stamped with a die or otherwise suitably formed so that the portion of the plaster intended for the reception of the medicament-as, for instance, pure or adulterated mustardis sunk or pressed inward from the face of the material to form a recess or receptacle having sides T. It will thus be seen that the formation described is substantially like the cup. As shown in Fig. l, a portion of the plaster intended for the edge or edges or the edges of the divisions of the plaster may be provided with holes or perforations C, thus making the edges or fiaps of the plaster porous. In Fig. 2 the edges or flaps D are shown as being non-porous.

(No specimens.)

The cavity or recess E in the material of which the plaster is formed should not be quite filled with the medicated mixture F, for room should be allowed for expansion of the mass when water is added and the plaster is placed in position on the patient. i

The irritation caused by the mustard or other suitable medicament will heat the skin somewhat beyond its normal temperature, and this heat will be confined within the cavity E at least as much as the heat was con- Iined in the old-style glass cup, and the plaster may, moreover, be kept in the desired position continuously for any desired length of time. It will not produce pain nor exert any nervous strain on the system, vand it will operate continuously and accentuate the action of the medicament until the irritation has been drawn from the inside to the surface.

The aps or edges of the plaster are preferably adhesive,a suitable adhesive substance G being applied thereto, and further advantages of my plaster reside in the fact that there is no evaporation, drying, or cooling, the plaster will remain fixed in position, there is no escape of fluids from the cupped dish or recess portion, and the heat is produced in a sealed recess or vesicle. If desired, the flaps may be medi-cated in order to add to the drawing action of the plaster.

In Fig. 3 a modification is shown in which the material of the plaster is provided with a dome-like structure to produce suction. The material of which the backing is made may be cupped, as before, and then a cover or dome H, of stiff material, secured on the back of the plaster by any suitable means, as by cement. This cap or dome should be shallow and made of any suitable stiff material, such as vulcanite or the like. back, as before, is cupped or recessed to fit within the dome or cap H.

In Fig. 4 the cap H is shown as outside of the recessed portion of the plaster and between the cloth A and the rubber B, while the medicament F is shown as a layer within the recessed portion of the plaster.

In Fig. 5 the cap H is shown inside of the recessed portion of the plaster and secured to the rubber, while the medicament F is placed in a layer on the inside of the cap. According to the construction described in the modi- The material ot' the cation of Figs. 3, 4, and 5, with a flexible cap secured to the material of the plaster in connection with the recessed or cupped portion, a slight vacuum may be produced beneath the plaster by manipulating the ilexible cap. By first applying the plaster tothe part affected and pressing the cap inwardly the medicament may be pressed tightly against the surface to which the plaster is applied, and then when the pressure on the cap is removed it will spring outwardly, and since the flaps or edges of the plaster are adhesive and the plaster is securely secured in position a vacuum will be secured beneath the plaster and a sucking action obtained.

It will be seen that the improved plaster in all the forms shown combines a raised back or a sunken face, edges, and sides, joining the edge portions with the raised or recessed portion of the back.

Obviously my invention may be embodied in varying forms, and some parts of my invention may be used without others. Therefore, without limiting myself to the construction shown and described,

y I claim, and desire to obtain by Letters Patent, the following:

l. A plaster-'having a sheet of impervious and flexible substance, the marginal or edge portions of which are flat and the middle portion of which is dished, forming a shallow depression with low sides, and medicament spread upon and carried by and in the said dished portion, for substantially the purposes set forth.

2. A plaster having a sheet of impervious and flexible substance, the marginal or edge portions of which are flat and the middle portion of which is dished, forming a shallow depression with low sides, and medicament spread upon and carried byand in the said dished portion, the said marginal portions being adhesive for attachment to the parts treated, for substantially the purposes set forth.

3. A plaster having a sheet of impervious and flexible substance, the marginal or edge portions of which are flat and the middle portion of which is dished, forming a shallow depression with low sides, and medicament spread upon and carried by and in the said dished portion, the said marginal portions being perforated, medicated, and adhesive, and forming an annular porous plaster, surrounding the said medicament.

4. A plaster having an impervious extended shallow dished portion forming a recess with low sides, a heating and drawing medicament carried in the said dished portion, marginal portions adapted to tit lat and tight against the part treated, and means for ereating slightsuction beneath the dishedportion when applied, substantially as set forth.

5. A plasterhaving an impervious extended shallow dished portion forming a recess with low sides, a heating and drawing medicament carried in the said dished portion, marginal portions adapted to tit lat and tight against the part treated, and a relatively stiffer cup or cap for creating suction, for substantially the purposes set forth.

6. A plaster having an impervious extended shallow dished portion forming a recess with low sides, a heating and drawing medicament carried in the said dished portion, marginal portions adapted to lit flat and tight against the part treated, and a relatively stiffer cup or cap secured to the dished portion of the plaster for creating suction, for substantially the purposes set forth.

7. A plaster having an imperforate and impervious center portion, medicament applied thereto for causing heating of the skin, and having a surrounding marginal porous plaster to coact therewith, for substantially the purposes set forth.

In testimony whereof l have signed this specification in the presence of two subscribing witnesses.

FREDERIC J. NASH.
